WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 642,471, dated January30, 1900. Application filed September 25, 1899. Serial No. 731,692. (Nomodel.)

T0 @ZZ .whom it may concern.-

Be it known that I, THEoDoRE J. P. MAUS, of the city of St. Louis, Stateof Missouri,phave invented certain new and useful Improvements inWindow-Screens,of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart'hereof.

My invention relates to window-screens;

'and it consists of the novel construction, com- Figure 1 is afrontelevation of a window,

showing my complete invention placed in position therein. Fig. 2 is ahorizontal sectional view of the window-screen. Fig. 3 is an enlargedvertical sectional view of the screen with parts broken away, showingits connection with the bottom rail of the Window-sash. Fig. 4 is asectional perspective view of a portion of the window-screen. A

In the construction'of my invention I provide two frames 1 and 2, eachconsisting of vertical strips 3 and a horizontal strip 4, one located atthe top and one at the bottom. Their ends 5 are supported by anangularlybent metallic strip 6, which is arranged to lit in slots 7,arranged in said horizontal strips a short distance from the end 5thereof. In each of the vertical strips 3 is formed a groove 8. This isfor the purpose of allowing said strips to be placed over a guide-strip9, which is of the ordinary construction and secured to the innervertical surface ofthe windowframe 10. (See Fig. l.)

The adjusting feature of the invention is provided by the arrangement ofthe horizontal strips and each of which is constructed with a dovetailedgroove 11. (See Figs. 3 and 4.) On their inner surface and in one of thestrips is placed a block 12, which is generally about one inch in lengthand is arranged to iit within (see Figs.- 3 and 4.)

The horizontal strips at the top and bottomL are exact duplicates. Thevertical strips 3 (see Fig. 2) are composed of two parts 15 and 16, andbetween the same is fastened one end 17 of the screen 14, and the otherend of the screen is fastened in any desirable manner to the angularstrip 6. The parts 15 and 16 each contain a portion of the groove 8, andwhen the screen is placed between the same they are secured together inany desirable manner.

In order to provide a tight joint upon the upper and lower horizontalstrips to prevent insects from passing between the upper horizontalstrips and the horizontal bar 18 of the window-sash, place a strip ofthin material 19, such as tin, dac., and secure the same in anydesirable manner to the outer portion of the strip, as shown at 20, andthe same is passed over the top and extended downwardly on the inside,as shown at 21. On this side is also secured in any desirable manner tothe inner portion of the strip 4 a strip of like material 22 and passedover the strip 19 and extended around the outer surface, as shown at 23.This arrangement will allow both of the strips in connection with thegroove 11 to telescope one within the other and yet provide'an evenappearance on all sides. The material 22 when placed in position withinthe window is brought into direct communication with the side 24 of thelower bar 18 of the window-sash, thus making a tight joint.

These strips 19 and 21 fit so closely around serve the double purpose ofretaining the desired adjustment of the screen and of forming a closejoint with the sash of the window at the top of said screen and with thewindow-frame at the bottom.

The arrangement of the two screens of both sections is such that at thepoint 25 (see Fig.

. strips of the screen.

2) they will be brought close together, so as to also prevent anyinsects from passing between said screens.

The angular strips (3 are constructed of thin lightvmaterial and ofsmall design, so as not to obstruct the free passage of air through thescreen and also to present a neat appearance.

The operation of my invention is as follows: I first secure to thewindow-frame l0 the s'trips 9. I then place the screen within the.window and adjust the same sidewise, bringing the grooves 8 incommunication with the strips 9. This I do by pressing outwardly uponthe vertical strips 3 of each screen. The same is held in thisadjust-ment by the tight fitting of the metallic strips 19 and 22, andthe same will be in readiness to be raised or lowered upon theguide-stri ps 9, as desired. The bottom Window-sash is raised so as tobring the cross-bar 18 at its highest point and will communicate Withthe top` horizontal This screen may also be made of any desirableheight, so as to operate as described no matter at what height the lowersash may be placed.

I claim- 1. In an adjustable Window-screen, horizontal strips composedof two parts slidingly secured together and having a metallic stripattached to each of said parts, said metallic strips fitting closelyaround said parts, one above the other, substantially as specified.

2. An adjustable Window-screen of two sections, having horizontal stripscomposed of two parts in each of which is a groove, a guide-blockrigidly held in one of said grooves and adapted to slide within thegroove in the other section, and a metallic strip attached to each ofthe parts forming said horizontal strips and fitting closely around saidstrips, one over the other, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.
